The people at Hiroshema and Auschwitz did not have control, it was controlled by other people. But, a person can control their own self. I read about a guy in Auschwitz who used to be a professor at a college in Berlin before the Nazis came to power. While in the camp, he lost his wife and children, but he never gave up hope that the camp would be liberated and he would resume his teaching at the same university. He never gave up hope. When the allies liberated the camp, he took up teaching at the university again. You CAN change your outlook which will change your life but you can not change what others do to you (e.g. Auswitz, Hiroshima, Nagasaki.) but you can choose how you will react to it.
